Glossary Total Antioxidant Capacity

measure of a sample's ability to neutralize free radicals

Total Antioxidant Capacity (TAC) is a measure of the combined antioxidant effect of all the compounds present in a sample, such as blood, food, or tissue. It reflects the ability of these compounds to neutralize free radicals, which are unstable molecules that can cause cellular damage and contribute to aging and diseases. TAC is important in both research and clinical settings to assess the antioxidant status and potential health benefits of various substances.

community Efficacy and Tolerability of N-Acetyl-Cysteine for Treatment of The Early-onset Androgenetic Alopecia in Men

26 upvotes 4 years ago

N-Acetyl-Cysteine (NAC) was found to improve hair parameters in men with early-onset androgenetic alopecia, showing increased terminal hair count and decreased vellus hair count, with good tolerability. NAC, used alone or with minoxidil, may help due to its antioxidant properties, though its effectiveness can vary among individuals.
